Legal claims defining the scope of protection, as filed with the USPTO.
1. A display device comprising: a thin film transistor array disposed on a substrate; a light-emitting array on the thin film transistor array; a passivation layer on the light-emitting array; and a touch electrode array on the passivation layer, wherein the touch electrode array comprises: a plurality of first electrodes arranged in a first direction, the plurality of first electrodes including a first touch electrode having a first metal mesh pattern and a first floating unit being separated from the first metal mesh pattern; and a plurality of a second electrodes arranged in a second direction that intersects the first direction, the plurality of second electrodes including a second touch electrode having a second metal mesh pattern, wherein the first metal mesh pattern includes a first line electrode arranged in a third direction and a second line electrode arranged in a fourth direction that intersects the third direction, and the second metal mesh pattern includes a third line electrode arranged in the third direction and a fourth line electrode arranged in the fourth direction, and wherein the first floating unit includes a plurality of segments.
2. The display device of claim 1 , wherein the first metal mesh pattern further comprises a protrusion protruding from the first metal mesh pattern located in a region adjacent to the second metal mesh pattern and facing the second metal mesh pattern.
3. The display device of claim 1 , wherein the plurality of first electrodes further comprise a bridge for connecting two first touch electrodes adjacent to each other in the first direction, and the plurality of second electrodes further comprise a connection mesh pattern for connecting two second touch electrodes adjacent to each other in the second direction.
4. The display device of claim 3 , wherein the bridge of the plurality of first electrodes overlaps at least the two first touch electrodes of the plurality of first electrodes with an interlayer dielectric film between the bridge and the two first touch electrodes.
5. The display device of claim 4 , wherein the bridge is connected to the at least two first touch electrodes through contact holes located in the interlayer dielectric film.
6. The display device of claim 4 , wherein the bridge overlaps the connection mesh pattern with the interlayer dielectric film therebetween.
7. The display device of claim 1 , wherein the second touch electrode further comprises a second floating unit being separated from the second metal mesh pattern.
8. The display device of claim 7 , wherein the first floating unit is electrically insulated from the first metal mesh pattern, and the second floating unit is electrically insulated from the second metal mesh pattern.
9. The display device of claim 1 , wherein the third direction and the fourth direction are diagonal directions.
